Long-range spin exchange for 2D qubits architectures

Electronic devices exist everywhere in our daily life. We can find them inside complex tools like mobile phones or laptops, but also in simple instruments such as clothes irons, ovens, or home digital thermometers. Nowadays, industries fight hard to reduce their sizes. This is not just for a reason of miniaturization. In general, smaller circuits consume less energy and are faster. The typical dimension of a transistor (the brick of the electronic circuits) currently used in industry is today, about 0.2 nanometers, about 100 silicon atoms wide. But at these small scales new phenomena, which were masked by the size of the device, start to be dominant. We call these effects quantum effects. Nowadays, the question is: Can we make use of these new effects to create a new type of computer? The answer to this question is yes. Scientists believe that a new kind of computation may be developed making use of these quantum properties. Furthermore, it is predicted that these new computers will be very powerful and have a tremendous impact on a vast number of applications. Because it is based on quantum effects, we call it: Quantum Computers. While not definitive (a large number of researchers are still working on the implementation of this kind of computation), we think that with this new type of electronics we will be able to predict the behavior of very large and complex systems. The implication of a computer that could handle much larger quantum systems is endless. Quantum simulations would revolutionize research areas that range from chemistry, medicine (with new generations of drugs and cancer cures) to material science, etc... In our project, we will focus on making a small quantum processor and we will address two main questions. Firstly, we will investigate a new type of material in which the quantum processors are fabricated. Secondly, we will optimize the interconnectivity within the quantum processor. We expect that the operations made in this new kind of quantum processors will be of much higher quality. We anticipate that by the end of this project we will be able to operate new quantum algorithms. We also believe that this new type of devices will give new insight into the design of the next generation of quantum electronics.
